PDS-08® is the first 9-strain pediatric synbiotic to be studied in a double-blind, randomized 12-week trial in a pediatric population, demonstrating that it is tolerable and health-promoting for children and adolescents. The following benefits were observed in the composition as a whole:
Studied in a pediatric population 1 to support digestive function and regular, healthy bowel movements in children with occasional constipation.2
Maintains healthy bowel movement regularity1 among non-constipated2 children without creating hyper-frequency of bowel movements.
No observed side effects or GI distress (such as pain, bloating, gas, diarrhea1) as commonly reported with many fiber-based dietary supplements, probiotics, and high-dose fermentable prebiotics.
Significantly enriches Bifidobacterium3 in the pediatric gut microbiome as demonstrated via metagenomic shotgun sequencing.4
Significant increase in the concentration of SCFAs present in the colon compartment of SHIME®,5 suggesting that PDS-08® supports the production of SCFAs in the lower gut.
Easy, frequent bowel movements.Studied in a pediatric population1 to support digestive function and regular, healthy bowel movements in children with occasional constipation.2
Promotes healthy regularity.Maintains healthy bowel movement regularity1 among non-constipated2 children without creating hyper-frequency of bowel movements.
Exceptionally well tolerated.No observed side effects or GI distress (such as pain, bloating, gas, diarrhea1) as commonly reported with many fiber-based dietary supplements, probiotics, and high-dose fermentable prebiotics.
Increase of Bifidobacterium3.Significantly enriches Bifidobacterium3 in the pediatric gut microbiome as demonstrated via metagenomic shotgun sequencing.4
Production of Short-Chain Fatty Acids in vitro.Significant increase in the concentration of SCFAs present in the colon compartment of SHIME®,5 suggesting that PDS-08® supports the production of SCFAs in the lower gut.
In addition to conducting a trial on the PDS-08® formulation as a whole, all strains included have been studied in preclinical research and/or clinical trials in pediatric populations.
Formulated to support overall gastrointestinal function and healthy digestive responses.

How bacteria are cultured impacts their viability. We optimize our biofermentation for pH, temperature, and 28 other critical growth factors. Our mediums contain no meat or dairy.
7 of the 9 strains are microencapsulated with a lipid coating to further protect from stomach acids, digestive enzymes and bile salts during digestion. This also means that refrigeration is not required.
We do extensive lot-to-lot testing at each step and on the final product. With 50+ QA/QC checkpoints, we monitor purity and strength under both US and EU protocols, including cGMP + HACCP.
All ingredients and their included dosages have been specifically studied in a pediatric population.

PDS-08®PediatricDailySynbiotic-Monthlyrefill1 Study in children specified daily use over 12 weeks.
2 Rome IV criterion for constipation includes less than 3 spontaneous bowel movements per week.
3 Native, commensal bacteria found in the human gut microbiome that are linked to the maintenance and improvement of digestive and immune function.
4 The presence of Bifidobacterium increased significantly in the stool among children taking PDS-08® over 12 weeks in a placebo-controlled clinical trial.
5 The Simulator of the Human Intestinal Microbial Ecosystem (SHIME®) is the closest in vitro system developed to simulate digestion and the gut.
Consistent, daily use is important. Here's why: probiotics are generally transient—meaning they travel through the digestive tract interacting with immune cells, gut cells, dietary nutrients and existing bacteria along the way before eventually exiting the body. This is why consistent, daily consumption is important to activate specific benefits.
Each component of the PDS-08® experience is designed with simplicity and 'how-do-I-get-my-kid-to-do-this-daily' in mind.1
1 While probiotics are a science, parenting is not—however your child prefers to take PDS-08® each day, that is the best way.
